Claims
- 1. In a medical device for enabling a rescuer to administer mouth-to-mouth resuscitation to a victim while maintaining a sanitary barrier between victim and rescuer, which device includes:
- a sheet of a flexible material forming a barrier to micro-organisms, said sheet being dimensioned to completely cover the victim's mouth, said sheet having an opening and a shaped portion of circular form which surrounds said opening and is shaped to allow the rescuer's lips to form an air-tight seal with the victim's lips when the rescuer is blowing air into the victim's mouth, said sheet, including said shaped portion, being formed to permit the victim to exhale without obstruction when the rescuer's lips are withdrawn from said sheet;
- a tubular member defining a confined air passage extending through said opening and having a first portion located to be inserted into the mouth of the rescuer and a second portion located to be inserted into the victim's mouth and over the victim's tongue when said sheet is in place; and
- means defining a one-way valve fastened to said tubular member for permitting free passage of air only from the rescuer to the victim,
- the improvement wherein said valve is supported by said first portion of said tubular member.
- 2. A device as defined in claim 1 wherein said sheet, said tubular member and said valve are constituted by a one-piece molded member.
- 3. A device as defined in claim 2 wherein said molded member is of a silicone rubber.
- 4. A device as defined in claim 3 wherein said silicone rubber is a 50 Durometer silicone rubber.
- 5. A device as defined in claim 1 further comprising a second tubular member of a rigid material held in place relative to said first-recited tubular member to surround the air passage and extending along both said first portion and said second portion of said first-recited tubular member, said second tubular member serving as a bite block to prevent the victim from closing the air passage and to prevent the rescuer from deforming said valve.
